Hi, everyone:

This is a question puzzled me for a long time, what's the meaning of
"packaged" in the air condition system?

ASHRAE 90.1 appendix G shows 8 types of the different HVAC systems in
the table G 3.1.1 B(see the illustration below), but I can't make the
difference between the 8th form others.

What should I do in the simulation if a HVAC system is "packaged"? And
what about the "unpackaged" ? You can see that this is the only
different between item 7 & 8 .

Anyone who kindly gives tips will be appreciated.

Best wishes from Joey in China.
